ab: From the text: By working through well-designed tasks, students can expand
their thinking about mathematical ideas and their approaches to solving
mathematical problems. They can come to see the value of looking at
tasks from different perspectives and of using different
representations. This article discusses four tasks that encourage high
school students and preservice secondary school mathematics teachers to
think flexibly about mathematical concepts and problems. Appropriate
use of these tasks challenges learnersâ€™ intuitions while broadening
and deepening their knowledge of mathematical concepts through the
linking of multiple representations.
